Mr McClintock, who was from the Galliagh area, was killed instantly when the car he was travelling in collided with another car on Saturday afternoon outside the village of Newtowncunningham in Co Donegal.

Orla O'Reilly, who was in her 30s, was also pronounced dead at the scene, while a third man remains in a critical condition in hospital.

At the Requiem Mass, Parish Priest Fr Micheal McGaughey prayed for all of the victims of the tragedy.

He told the congregation that Mr McClintock was a devoted family man who was an outdoor sports enthusiast, and that he had high hopes for his children.

Miss O'Reilly, who is originally from Cavan but was living in Muff, Co Donegal, was also laid to rest yesterday.
